FLUCTUATIONS OF SOLID SUBGRADE

For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version). ABSTRACT The results of measurements of the characteristics of vertical oscillations of the base of the main site of a stable embankment of subgrade of a railway track under the influence of an electric locomotive VL-80 with different speeds of movement are given. Experimental studies were carried out in Kazakhstan on the section of the enlarged Almaty maintenance section. The dependencies of the parameters of the oscillatory process on the speed of locomotive motion that can be used as evaluation criteria in the development of railway embankment monitoring systems are revealed. The expediency of further experimental studies in the zones of problem embankments with soils prone to thixotropy was noted. Keywords: railway track, subgrade, main platform, vibration speed, vibration displacement, vibration acceleration, vibrogram, accelerogram, amplitude-frequency characteristics.
